FOUR-TUB ELECTRIC BATH.

SPECIFICATION forming part of Letters Patent No. 620,254, dated February 28, 1899. Application filed December 15, 1898. Serial No. 699,318. (No model.)

To all whom it may concern:

Y Be it known that I, CARL EMIL SOHNEE, doctor of medicine, a subject of the Emperor of Austria-Hungary, residing at Carlsbad, Austria-Hungary, have invented certain new and useful Improvements Relating to Four-Tub Baths, of which the following-is a specification.

This invention relates to an arrangement for carrying out several kinds of treating the human body-i. e., commonly by electrification as well as by cataphoresis or introduction of medicaments in the human body.

The apparatus represents a four-tub bath with four separate tubs, each of which receives only one limb at a time,thesefour tubs being so combined with an adjustable chair that the body to be treated may assume a comfortable position during the treatment. The four separate tubs can be connectedwith the electric circuit as required, so that the current flows through the body in fifty different directions. For seating the body as comfortablyas possible the chair combined with the four tubs is so constructed thatthe arm-tubs may be elevated and lowered as well as removed and turned horizontally. The body of the patient is brought in the right position to the four tubs by elevating or lowering the movable seat of the chair.

The fifty different current directions (bathing combinations) are shown in the accompanying drawings in Figures 1 to 50, wherein the reproductions of a human body by its arrows represent the special manner of treatment, while in the squares the same schematically is shown. According to the kind of connection of the tubs with the electric circuit and by reversing each kind, the current flows through the bod yin the directions hereinafter described. Using all the four tubs the fourthe seat is illustrated, in Fig. the seatframe, while Fig. 56 shows the seat itself.

The electric current flows as follows: A, Fig. 1: The current flows from both arms through the body in vertical direction downward to both legs. A Fig. 2: By reversing the direction A the current flows from both legs through the body upward to both arms. A Fig. 3: The current flows from the right limbs through the body horizontally from the right to the left'and through both left limbs. A, Fig. 4.: By reversing the direction A the current flows from the left limbs horizontally through the body to both right limbs. A Fig. 5: The current flows from the right arm through the upper part of body (horizontally from the right to the left) and through the left arm, as well as through the right-hand part of body, (vertically downward,) and through the right leg,at the same time through the left-hand leg and the lower part of the body (horizontally from the left to the right) and through the right leg, as well as through the left part of body, (vertically upward,) and through the left arm. A Fig. 6 By reversing the direction A the current flows along the same lines in the direction opposite to that shown in A A Fig. 7: The current flows from the upper limbs through the body and theleft leg (on the right hand vertically downward, as well as diametrically from the right to the left downward and in the lower part horizontally from the left to the right) and through the right leg. A Fig. 8: By reversing the direction A the current flows along the same lines as in Fig. 7, but in opposite direction of that in Fig. 7. A Fig. 9: The current flows from both upper limbs through the whole body (on the left hand vertically downward and diametrically downward from the right to the left, as well as in the lower part of body horizontally from the right to the left) and through the left leg.

A Fig. 10: By reversing the direction A the current flows along the same lines as last described, but in opposite direction. A, Fig.

11: The current flows through the lower limbs, the right arm, and the whole body, (on the left hand vertically upward and diametrically from the right to the left'upward and in the upper part horizontally from the right to the left,) as well as through the left arm.

A, Fig. 12: By reversing the direction A, Fig. 11, the currentfiows the same way as that of the kind A, butin opposite direction. A Fig. 13: The current flows from both lower limbs through the body, the left arm, (on the right hand vertically downward, as well as diametrically from left to right upward and in the upper part horizontally from the left to the right,) and through the right arm. A, Fig. 14: By reversing the direction A the current flows in opposite direction, but along the samelines.

If one or two tubs are not connected with the source of electricity the following thirtysix combinations can be made, twenty-four of which are produced by disconnecting one tub, (combinations B,) while the twelve combinations O are obtained by disconnecting two tubs.

After having disconnected one of the tubs the electric current flows as follows: B, Fig. 15: The current flows from both upper limbs through the body and the right leg. B Fig. 16, shows the reversal of the combination B, wherein the current flows along same path but in an opposite direction. B Fig. 17: The current flows through both upper limbs, the body, (on the left hand vertically downward, as well as diametrically downward from the right to the left,) and the left leg. B, Fig. 18: By reversing the direction B the current flows through the left leg, the body. (on the left hand vertically upward, as well as diametrically upward from left to right,) and through both upper limbs. B Fig. 19:

The apparatus used for carrying out the above-stated fifty bathing combinations is, as already mentioned, so constructed that the patient therein gets a comfortable and natural position.

The apparatus comprisesfour separate tubs to, (t 1), and 19 of non-conducting material, which may not be disturbed by the influences produced by the treatment. Such a material may be preferably porcelain, but any other material adapted for this purpose may be employed. The tub, with its oblong roundedoff and conical shape, may be longer (d and a or higher, (1) and 19 according to its purpose?,'. 6., to receive an arm or a leg. The four tubs are combined with an especiallyconstructed chair, so that the tub can be brought into the most suitable position for receiving the limbs.

The arm-rests are carried by racks c, reaching through the cross-rails arranged on both sides of the chair. Upon each of those crossrails a bar 6, mounted on a vertical pivot, is arranged, the ends of the bars 6 being so sharpened that they fit with the gaps in the teeth of the racks c. For elevating or loweraround their pivot. When the arm-rest is brought to the desired height, the bar 6 may be turned back in the plane of the racks 0. Both arm-rests consist of three plates, the lowest of which, fand f, is fastened upon the racks 0. Plate f, as well as plate f, has two dovetailed grooves, wherein movable bars 9 g and g g are loosely provided. The bars 9 and 9 have a double-dovetailed cross-section and lie with their upper dovetailed halves in corresponding grooves of plates h and h, the latter thereby being movable along the bars g 9. Upon the plates hh plates and is are provided, the latter being connected with the first by pivots 'i 'i, around which pivots the plates is k can be horizontally turned. By this construction I render it possible to bring the arm-tubs in any required position.

The seat-plate d, Figs. 54 and 56, is carried by a frame, Figs. 54 and 55, supported by racks Z. The frame of the seat is composed of four bars p, forming a trapezium, the four corners of which carry the racks I. On each side of the chair a rail n is provided, Fig. 54, through which the racks Z are put and whereupon a bar 0 lies, the sharpened ends of which may fit with the gaps in the teeth of the racks l. The trapezium-shaped frame is provided with a middle bar 10. In all the three bars 19 p 10 two dovetailed grooves are secured for receiving two corresponding bal s q, attached to the seat-plate. The seat arranged in this manner may be covered with an insulating covering, the upper end of which reaches beyond the back-support r.

A bracket m can be attached to the backsupport of the chair for carrying, if desired, electric controlling apparatus .or the like.

Each of the four tubs is provided with two guides 8, adapted to receive electrodes of corresponding dimensions, preferably manufactured of preparedhard carbon. To the binding-screw of each electrode a conducting-wire is attached, but the two wires of each tub are afterward connected, so that they form onlyone conducting-wire. Therefore in each separate tub only, positive or negative current at the time can be introduced and never positive and negative can be introduced at the same time. 7

When the tubs are filled with liquid (water, with or without medicaments) to the necessary height, the apparatus is ready to be used.

Between the four tubs ct a b b the body of the patient is the single conducting means for the electric current, the latter being therefore compelled to flow through it. The electric current introduced in the tubs fiows through the insulated body in the abovenamed fifty combinations according to the particular circuit combination, which depends upon how many and which tubs are connected with the positive pole and how many and which tubs are connected with the negative pole. All these fifty combinations can be employed for four different kinds of treatment-first, for galvanization; second, for faradization; third, for galvano-faradization; fourth, for cataphoresis relatively for introduction of medicaments in the human body-45. e., the human body can be treated in the fifty different combinations by galvanic current, in the fifty combinations by faradic current, in the fifty combinations by (inbined galvanic and faradic current, and, further, by the fifty combinations medicaments can be introduced in the human body.

It will be seen from the foregoing that by my present invention I place at the disposal of medical men two hundred different methods for treating the human body, from which they can choose the special combination or combinations adapted to the individual qualities of the patient.

Having thus described my said invention, what I claim is 1. Electric four-tub bath with four absolutely-separated tubs of non-conducting material (preferably porcelain) each of which receives one limb and which can be connected in different combinations for every kind of treatment of the body combined with an adjustable bathing-chair, substantially as described and forthe purpose set forth.

3. Electric four-tub bath with four absolutely-separated tubs of non-conducting material (preferably porcelain) each of which receives one limb and which can be connected in different combinations for every kind of treatment of the body combined with an adjustable bathing-chair, the seat-plate of which can be elevated and lowered and removed in front, substantially as described and for the purpose set forth.

4. Electric four-tub bath with four absolutely-separated tubs of non-conducting material (preferably porcelain,) each of which receives one limb and which can be connected in different combinations for every kind of treatment of the body, combined with an adjustable bathing-chair, the seat and the back support of which is covered with an insulating-covering, substantially as described and for the purpose set forth.
